Abstract

A simplified method is proposed in this paper for simultaneously evaluating internal solid-film and external fluid-film capacity coefficients of mass transfer from the breakthrough curve of an adsorption bed. The method is based on a graphic technique of dividing a breakthrough curve into two pieces and is applicable to all favorable systems for adsorption. The two film capacity coefficients are directly obtained from the ratio of the time interval between the breakthrough point and the dividing point to that between the breakthrough point and the exhaustion point. Diagrams for adsorption systems with K<0.5 for Langmuir isotherm and β <0.5 for Freundlich isotherm are shown. Diagrams for graphically obtaining a diffusion coefficient from a breakthrough curve are also shown, and several examples of the evaluation are given.
